Hi
Thanks for the quick reply.

The symptoms are as follows
When connected to the wlan I can ping the firewall but not one of our
servers, the server ip times out

This is a ping from one of the laptops connected to the wlan
>ping 192.168.1.1

When I plug it in on the lan its works perfect with no time outs.

How come is the MTU so low on the ath0, but its working at full speed? The
wlan signal is stronger then any of our other wireless devices I've ever
used before
